This review discusses how macro-environmental factors such as intradermal adipose tissue and sex hormones influence hair and feather stem cell niches, suggesting environmental targets for regenerative medicine, but reports no new clinical results.

This study found that decision-making effects related to time of day and chronotype were only significant when using RNA-based chronotype measurements, indicating molecular clock differences may influence these behaviors.

This article discusses the hair follicle's regenerative cycles and the molecular mechanisms influencing them, emphasizing the need for therapeutic targeting of the "hair cycle clock" to manage hair growth disorders, without reporting new research findings.

This review discusses the hair follicle cycle's complex regulation and highlights the potential for targeting catagen control in future therapies without presenting new experimental data.

In this study, researchers found that Hdac1 and Hdac2 are crucial for maintaining the quiescence and survival of dermal papilla cells in the hair follicle, regulating the hair cycle by controlling cell-cycle genes and Wnt signaling.

In this study, silencing BMAL1 and PER1 genes increased melanogenic activity in follicular and epidermal melanocytes, suggesting that peripheral circadian clocks may regulate melanin pigmentation.

This study analyzed gene expression changes during the autumn coat color change in mountain hares and found conserved gene regulation with snowshoe hares, highlighting its role in seasonal camouflage adaptation.

In this study, researchers developed a simple, non-invasive method to monitor circadian gene expression using whole hair root cultures, finding that elderly dementia patients' peripheral clocks still oscillate similarly to younger, healthier individuals, which suggests cellular senescence minimally affects some aspects of circadian rhythms.

In this review, the authors discussed how the circadian clock influences hair follicle regeneration by regulating metabolism, suggesting potential new targets for hair loss treatments.
